Several flora and fauna species found in arid areas have adapted themselves to collect water by developing unique structures and to intake the collected moisture. Apart from the capture of the moisture and fog on the surface, water transport and collection both play an important part in fog-harvesting systems as it prevents the loss of captured water through evaporation and makes the surface available for the capture of water again. Here, we report the remarkable fog collection and water…

Copper Oxide Microtufts on Natural Fractals for Efficient Water Harvesting

A multiscale surface capable of rapidly nucleating, growing, and directional transport of the water droplets and the role of the microtufts, fractal structures, and the orientation of leaf veins was investigated to provide valuable insights into the design and fabrication of sustainable and efficient fog harvesting systems.

Mangifera indica Leaf (MIL) as a Novel Material in Atmospheric Water Collection

Here, Mangifera indica leaves (MILs) have been used to collect atmospheric water for the first time. This novel material has been viewed by mankind as environmental waste and is mostly discarded or

Leaf prickle hairs and longitudinal grooves help wheat plants capture air moisture as a water-smart strategy for a changing climate

The leaf features like trichome density, gradient grooves, and leaf wettability determine the efficiency to capture air moisture for self-irrigation in the wheat plant. Plants in water-scarce

Leaf rolling dynamics for atmospheric moisture harvesting in wheat plant as an adaptation to arid environments

Plant species surviving in the arid regions have developed novel leaf features to harvest atmospheric water. Before the collected water evaporates, it is absorbed and transported for storage within

ABSTRACT The rice leaf, combining the surface properties of lotus leaves and shark skin, presents outstanding superhydrophobic properties motivating its biomimesis. We created a novel biomimetic

Effect of the Angle of the Crossed Fibres of a Fog Harvester on its Collection Efficiency

Results show that as the angle of fibres changes, the effective collection rate per unit length of the fibre keeps unchanged, except near the maximum/minimum limits of the angle, where the collection rate drop significantly, caused by clogging according to the experimental observations.

Biomechanics in plant resistance to drought

This review examines how the factor of mechanics acts on the multi-level plant functions under drought stress, including water transport, tissue deformation, cell growth, cell movements, molecules interaction and signal pathway.

Water harvest via dewing.

The optimal surface conditions found in this work can be used to design a practical device that harvests water as its biological counterpart, a green tree frog, Litoria caerulea, does during the dry season in tropical northern Australia.

The effects of surface wettability on the fog and dew moisture harvesting performance on tubular surfaces

This work compares the water harvesting performance of the surfaces with various wettability under two different harvesting conditions–dewing and fogging, and shows that the different harvesting efficiency of each surface under these two conditions can be understood by considering the relative importance of the water capturing and removal efficiency of the surface.
